XFillArcs

Syntax

XFillArcs(display, d, gc, arcs, narcs)
      Display *display;
      Drawable d;
      GC gc;
      XArc *arcs;
      int narcs;

Arguments

display Specifies the connection to the X server.
d Specifies the drawable.
gc Specifies the GC.
arcs Specifies an array of arcs.
narcs Specifies the number of arcs in the array.

Description

For each arc, XFillArcs() fills the region closed by the infinitely thin path described by the specified arc and, depending on the arc-mode specified in the GC, one or two line segments. For ArcChord , the single line segment joining the endpoints of the arc is used. For ArcPieSlice , the two line segments joining the endpoints of the arc with the center point are used. XFillArcs() fills the arcs in the order listed in the array. For any given arc, XFillArcs() do not draw a pixel more than once. If regions intersect, the intersecting pixels are drawn multiple times.

Both functions use these GC components: function, plane-mask, fill-style, arc-mode, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use these GC mode-dependent components: foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

XFillArcs() can generate BadDrawable , BadGC , and BadMatch errors.

Diagnostics

BadDrawable A value for a Drawable argument does not name a defined Window or Pixmap.
BadGC A value for a GContext argument does not name a defined GContext.
BadMatch An InputOnly window is used as a Drawable.
BadMatch Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
